Long story short, GameSparks looks wonderful but I want to represent a lot of highly relational data in my game and I'm finding doing so through the existing NoSQL Metadata view to be immensely cumbersome.
I know that you can't just slap on a relational database option. It's a core, foundational change that can't be implemented quickly but I would love to see the ability to use a relational database.
Thanks for your input. As you say it would be a huge change to the core of the platform. May I ask what it is you are finding cumbersome at the moment exactly ? We are more than happy to help make your use of GameSparks as easy as possible.
